How to choose a supplier of vacuum coating equipment?
At present, the number of domestic vacuum coating equipment manufacturers is constantly increasing. There are hundreds of them and many abroad. So how to choose a suitable supplier among so many brands? How to choose the right vacuum coating equipment manufacturer? This It's up to everyone to identify, and now I will work with you to identify the vacuum coating equipment supplier that is really suitable for you.
1. Determine the level of the vacuum coating equipment manufacturer according to your product positioning. If your product is positioned in the mid-to-high-end market, you must choose mid-to-high-end equipment. On the contrary, you can choose mid-end or mid-to-low-end equipment. Of course, if the funds are sufficient, it is best to buy a mid-to-high-end device with richer performance and more stable quality.

2. The characteristics of high-end equipment, equipment stability must be good, and the selected accessories must be reliable. The coating machine itself is a complex system, including vacuum, automation, machinery and other systems. The unreliability of any component will cause The instability of the system will bring inconvenience to production. Therefore, a stable equipment must ensure that every component selected is reliable. Many people will naturally compare when buying a coating machine. There may not be a very big difference in the basic configuration of the coating machine and a 2 million coating machine, but it is the mastery of some tiny details that makes a stable performance coating machine.

3. Look at which company's vacuum coating equipment is selected by well-known companies in the same industry. This is undoubtedly the least risky option.
4. At present, there are basically two types of vacuum pumping systems, one is a diffusion pump system and the other is a molecular pump system. The molecular pump system is a clean pumping system without the oil return phenomenon of the diffusion pump, and the pumping speed is relatively stable. Moreover, it is relatively power-saving, and the expenditure of electricity is a large part of the production and operation costs of coating enterprises. The regular maintenance of the pump system is very important, especially the regular replacement of the lubricating oil. Pay attention to the choice of the oil brand. The wrong choice can easily damage the vacuum pump.
5. The vacuum detection system currently basically uses a combination of composite vacuum gauges, thermocouple gauges and ionization gauges. When this combination encounters a process of filling a large amount of gas containing C element, the ionization gauge is easily poisoned and damages the ionization gauge. If the process of plating a gas containing a large amount of C element, you can consider configuring a capacitor film gauge.

6. Vacuum power supply, the gap between domestic power supply and imported power supply is quite obvious. Of course, the price is relatively favorable. A domestic 20KW intermediate frequency power supply is about 80,000, and an imported intermediate frequency power supply is 200,000. The performance and reliability of the imported power supply Performance and stability will be better. Domestic power supplies may be better in service than imported power supplies because they are produced in China.
7. Control system. Nowadays, many coating machines adopt fully automatic control, but the difference in automatic control is still very big. Most of them are still in semi-automatic state, which can truly realize fully automatic control, one-key operation of coating There are not many equipments, and whether to provide sufficient safety interlocks during operation in automatic control, the functional modules are also very different.
8. Do you need to configure a low-temperature trap PolyCold? The low-temperature trap can be said to be an icing on the cake. It can greatly increase the pumping speed, adsorb the condensable gas in the vacuum chamber on the cold coil, and purify the vacuum The indoor atmosphere makes the quality of the film better. In the hot and humid summer, the use of low temperature traps undoubtedly improves the production efficiency to a large extent.

9. Cooling water circulation system. The coating machine needs to be equipped with a cooling water circulation system. It is best to use deionized water for cooling water, which has a great effect on anti-corrosion, especially the welding bead of the vacuum chamber and some parts that are easy to rust. For good inhibition, some preservatives can be added to deionized water to prevent corrosion.
